IDEAL 36-309 TKO Hole Cutter 2 in Carbide

TKO™ Carbide tipped hole cutters offer the most efficient and clean cutter replacement for traditional knockouts, by making smooth holes in a fraction of the time at a fraction of the cost. Specifically designed to cut sheet metal, TKO cutters will even cut stainless steel with fine grained, carbide tips. The innovative design includes the exclusive SMOOTHSTART™ replaceable pilot drill, which guides the cutter to the surface, avoiding cutter damage and providing smoother holes. An integral over drill flange prevents cutter penetration beyond the sheet metal.
